Problems with viewing websites

We have XP Home and I.E.7. Some web pages will not load. Is this something to do with the security settings on I.E. or our firewall? (If it is the firewall I assume that the same pages would be blocked on our second PC which shares the wireless modem - would I be right?) If that is the case then it must be the I.E. settings as our second PC can access more pages than this one. How do I solve this problem?

I suppose brundle is suggesting that IE7 is still beta which is why it is suggested that you go back to the tried and tested bu old IE6, have you tried Firefox, it has tabs and most of the things that IE7 is trying to introduce.

I have the same problem and my ISP help desk could not solve it. It began with a credit card website happens now with the BT website. How can I remove IE7. It doesn't show using Control Panel, Add Remove software. I have Windows XP and recently installed WiFi to share Broadband with my wifes' laptop.We can view the websites on her laptop.Thanks in advance
